Unless otherwise stated, all the substituents are independent of one another. If, for example, there are a plurality of C₁₋₆-alkyl groups as substituents in one group, in the case of three substituents C₁₋₆-alkyl, one may represent methyl, one n-propyl, and one tert-butyl.

Within the scope of this application, in the definition of possible substituents, these may also be represented in the form of a structural formula. An asterisk (*) in the structural formula of the substituent is to be understood as being the linking point to the rest of the molecule. Moreover, the atom of the substituent which follows the linking point is referred to as the atom in position number 1. Thus, for example, the groups N-piperidinyl (I), 4-piperidinyl (II), 2-tolyl (III), 3-tolyl (IV), and 4-tolyl (V) are shown as follows:

If there is no asterisk (*) in the structural formula of the substituent, each hydrogen atom may be removed from the substituent and the valency thus freed may act as a binding site to the rest of a molecule. Thus, for example, VI may represent 2-tolyl, 3-tolyl, 4-tolyl, and benzyl
